Why Replace Your Collector Box Gasket?
Over time, collector box gaskets can deteriorate due to repeated thermal cycling, moisture exposure, and combustion byproducts. A worn or damaged gasket can result in flue gas leaks, reduced heating efficiency, nuisance pressure switch trips, and potential safety hazards. Replacing the gasket with a genuine Carrier OEM part restores proper system performance and ensures compliance with manufacturer specifications.
